Colin Kaepernick has shown time and time again that he is not interested in a purely celebratory version of patriotism.

On Thursday morning, the former 49ers quarterback shared a video on Twitter featuring quotes from Frederick Douglass’ famous July 5, 1852 speech delivered in Rochester, New York. Douglass, who was born into slavery, had been asked to speak on July 4 but declined, and his speech explains why.

“What, to the American slave, is your 4th of July?” Douglass asked in his hour-plus speech deriding the celebration of freedom when so many in America were not free.

The video on Kaepernick’s timeline shows drawings of lynchings, the Ku Klux Klan and more recent instances of police brutality.

“There is not a nation on the earth guilty of practices more shocking and bloody than are the people of these United States at this very hour,” Kaepernick wrote, quoting Douglass.

Earlier this week, the outspoken Kaepernick made waves when he halted Nike’s production on a Fourth of July sneaker featuring the Betsy Ross American flag, which was co-opted by white nationalist groups.
